Definitions

  • the present invention refers to Verdol type weave mechanics of the so-called double lift type and to weaving looms equipped with such mechanics.
  • Mechanics of the kind in question which are, for example, described in patent FR-1 523 252, generally comprise double hooks the two branches of which can cooperate respectively with the knives of one and the other of two claw frames moving in phase opposition, that is to say driven by reciprocating back and forth movements 180 ° out of phase.
  • Each branch is provided with an open step heel suitable for resting on one of the bars of an open step grid when the hook is to be kept high. In the free state, each hook rests on a bottom board defining the low position of the corresponding warp thread.
  • Means are also provided for acting according to a program, depending on the weave of the fabric, on one or other of the branches of the hooks in order to deflect them.
  • These known means are produced in the form of a train of bars acting on needles which cooperate with the branches of the hooks, the train of bars operating according to the reading of needles with respect to the perforations of a strip of paper which match the desired armor.
  • the needles In the idle state, the needles normally retain the hooks in the gripping position, their movements, called “press” in the art, bringing them into the erased position.
  • Verdol type mechanicals as described in FR-1,523,252, are unable to reach high operating speeds due to inertia, in particular the needles, and the reading time of the paper.
  • the hooks having a high inertia, they are a serious obstacle to rapid movement.
  • the blades are driven back and forth by two claw frames.
  • the the ends of the blades are each provided with a lug capable of being hooked in the high position on a knife when they are deflected by an electromagnet disposed between the two blades, while the lift spouts are permanently engaged or on the trajectory of two knives carried by claw frames.
  • This mechanism is of a completely different design compared to that of FR-1 520 252 since there are no hooks per se, these being replaced by all of the two flexible blades connected by a cord surrounding a pulley .
  • the main drawback of this mechanism is the existence of the pulley, the rotation of which results in overheating which is detrimental to good general operation.
  • this pulley wears out and a preventive change of several thousand pulleys must be planned during certain maintenance operations on this mechanism. This maneuver is long and requires specialized labor, which increases operating costs.
  • the improvements which are the subject of the present invention aim to remedy the aforementioned drawbacks and to allow the production of an armor mechanism of the kind described at the beginning of the present document, using double hooks which are capable of operating at very great speed.
  • the invention relates to a mechanical armor with double lift of the kind comprising a multiplicity of hooks each provided with two branches, mounted on a common base and respectively carrying a lift nozzle capable of cooperating with one of the knives. of two claw frames moving in phase opposition in a reciprocating movement, characterized in that said spout is controlled to move relative to said knife by an actuator disposed between said two branches and in that said hook also wears two open heels capable of cooperating with open step bars, said open step heels being controlled to move relative to said bars by said actuator.
  • the actuator can be an electromagnet supplied sequentially from a program in order to control the movement of the lifting lugs relative to the knives of the claw frames. It can also be a flexible retractor moved by an electromagnet or any other suitable device.
  • the invention also relates to a weaving loom equipped with a weaving mechanism as described above.
  • FIG. 1 a double hook 1 of a mechanism according to the invention in its low position. It can be observed that this hook has the shape of a U, the two branches 2, 3 of which are produced by flexible metal blades terminated respectively by a lifting nozzle 4, 5 curved outwards.
  • the central part or base 6 of the hook 1 rests against the upper face of a fixed bottom board 7 suitably drilled so as to allow passage to a cord 8 connected to a stringer and to each hook.
  • the mechanics according to the invention comprises two claw frames which have been shown schematically only for each of them a knife 11, respectively 12, these knives moving vertically, back and forth and in phase opposition .
  • an electromagnet is placed between the two branches 2 and 3 of each hook and, just below their lifting lugs 4, 5 when the hook is at rest against the bottom board 7 15 suitably fed sequentially from a program dependent on the weave of the fabric and carried out in known manner, for example in the form of a computer program.
  • the operation is as follows:
  • Figure 3 shows the phase following the position of Figure 1 when the knives 11 and 12 cross.
  • the lifter beak 5 and the branch 3 are moved in the direction of the electromagnet 15, which is not activated, by pressing the part lower knife 12 against the upper part of the lift nozzle 5.
  • the knife 12 drives the lift nozzle 5 from its path during its downward movement.
  • the spout 5 can be moved out of the path of the knife 12 by activating the electromagnet 15 which attracts the branch 3.
  • This variant avoids repeated mechanical friction between the lower part of the knife 12 and the upper part of the spout raises 5, but requires more activations of the electromagnet 15.
  • the electromagnet 15 is able to move the lifter nozzle 5, even if the latter is not opposite the electromagnet, since the blade 3 is metallic and capable of reacting to the magnetic field. induced by the electromagnet whatever the height of the hook 1 relative to the bottom plate 7, that is to say whatever the position of the electromagnet 15 in the space between the branches 2 and 3 of hook 1.
  • Each of the branches 2, 3 of the hook 1 is also provided at its lower part adjacent to the central part 6 with an open pitch heel 9, respectively 10, produced by means of an oblique segment in the direction of the bottom.
  • the mechanics also comprises an open pitch grid, two bars 13, 14 of which are shown on either side of the branches 2 and 3 of the hook 1 and outside of it.
  • FIG. 4 shows the extreme upper position of the hook once the knife 11 has reached its highest position and that consequently it begins its downward stroke.
  • the electromagnet 15 is not supplied and the hook begins a downward movement.
  • the open step heels 9 and 10 will rest on the bars 13, 14 of the open step grid 5.
  • the hook remains in its high position shown in FIGS. 4 to 6.
  • the electromagnet 15 is powered while one of the knives is on the point to descend, so that the two branches 2 and 3 of the hook 1 are deformed inwardly and come to bear against the electromagnet 15, as well as is shown in Figure 7.
  • the open pitch heels 9 and 10 are moved towards the inside of the base, so that when the hook descends, the heels 9 and 10 do not cooperate with the bars 13, 14 and that the base descends towards the board 7 under the effect of gravity or the restoring force of a spring not shown attached to the non-visible end of a heddle connected to the cord 8.
  • the hook continues to descend, as illustrated in FIG. 8, and when approaching the crossing of the knives 11 and 12, the electromagnet 15 is supplied to deflect the branch 2 of the hook so that its beak 4 is not gripped by the knife 11 which rises.
  • FIG. 9 illustrates the end of the downward movement of the hook after the supply of the electromagnet 15 has ceased.
  • the end of the downward stroke is illustrated in FIG. 10 in which the central part or base 6 of the hook rests against the fixed bottom board 7. We then return to a position similar to that of Figure 1 where the hook will be raised, in this case by the knife 12 which is ascending.
  • the electromagnet 15 is capable, not only of controlling the movement of the lifting lugs 4 and 5 relative to the knives 11 and 12, but also of moving the heels of open pitch 9 and 10 compared to bars 12 and 13.
  • FIGS. 1 to 10 is particularly simple since the whole of the hook 1, that is to say the two branches 2 and 3, the lifting lugs 4 and 5 and the base 6, is produced by a single curved rod on which the upper end of the cord 8 can be knotted.
  • FIG. 11 A second embodiment of the invention has been illustrated in FIG. 11 by representing two hooks in high and low positions.
  • the hooks which are assigned the general reference 100 comprise two strips made of spring steel and referenced 102 and 103, these strips corresponding to the branches 2 and 3 of the hook 1 of the preceding embodiment.
  • the upper free end of each strip 102, 103 respectively carries a lifting spout 104, 105 while its lower end is embedded in a massive and elongated base 106 having in cross section the shape of a rectangle.
  • the slats 102, 103 are preferably embedded relative to the two opposite small sides of this section.
  • the base 106 includes a shoulder 106 facing downward and which is intended to rest in the low position of the hook 100, against the bottom 7 of board that has not been shown in Figure 11.
  • the lower end of the base 106 has a hole 106 b to which is attached a cord 108 connected to the corresponding rail.
  • the widest part of the base 106 is also provided with a longitudinal light 106 c , the role of which will be better explained below.
  • each hook can be placed in a longitudinal cage suitable for guiding its base and its lamellae, this cage being constituted by two partitions 116 forming a slide for the base 106 of the corresponding hook and for an electromagnet 115.
  • this electromagnet 115 is provided, the upper end of which is assembled with the two partitions. The same applies to the lower part of the electromagnet 115.
  • each partition 116 is constituted in the form of a U-shaped profile comprising a web 116 a and two short wings 116 b , 116 c .
  • the wings 116 b and 116 c surround the base 106 of the hook at their lower parts, while the wings are reduced over the rest of its height to two low ribs 116 b 1 and 116 c 1 illustrated in FIG. 12.
  • two wings are kept at a very low height substantially in the middle of the part of the partition which is reduced to the veil 116 a and to the ribs 116 b 1 and 116 c 1.
  • the two ears which are formed are referenced 116 d and 116 e by the remaining part of the wings mentioned above.
  • two partitions 116 can be assembled, their wings facing each other to form the cage mentioned above by carrying out this assembly by means of bolts or rivets passing through holes 116 f , 116 h .
  • the connecting element passing through the holes 116 f also passes through a hole 117 a of the core 117 so as to assemble the latter to the two partitions.
  • the element passing through the holes 116 g of the partitions also passes through a hole 115 a of the electromagnet to effect its fixing, while the assembly element passing through the holes 116 h of the partitions passes through the light 106 c of the base 106 of the hook 100.
  • a closed cage is thus produced on the lower part of the partitions 116, the wings of which come into contact with each other, as well as the ends of the ears 116 d and 116 e which then form the open pitch bars corresponding respectively to those 13 and 14 of the embodiment of Figures 1 to 10.
  • the ribs 116 b 1 and 116 c 1 form over their entire length a slide for the corresponding strip, as more particularly illustrated in figure 12.
  • a single cage is not used, but two end partitions 116 and a mupliplicity of intermediate partitions 118 affecting an I-shaped section whose web is referenced 118 a , while its wings are identified 118 b , 118 c .

  • This embodiment differs from the previous one in that two open pitch heels 209 and 210 are carried by two flexible strips 219 and 220 embedded in the base 206.
  • An orifice 202 a and 203 a is formed respectively in each strip 202 and 203 so as to allow the displacement of the heels of open step 209 and 210 perpendicular to the strips 202 and 203.
  • An electromagnet 215 controls the vertical movement of a rod 216, housed in the space between the branches 202 and 203, which is extended by a spacer 217 formed by two flexible steel blades 217 a and 217 b fixed to the lower end of the rod 216.

  • the rod 216 When the electromagnet 215 is activated, the rod 216 is moved in the direction of the base 206, that is to say downwards and, as the spacer 217 bears on the fixed bar 229, the ends 217 c and 217 d are spaced from one another and push outward the lamellae 202 and 203 when the device is in the position of FIG. 15 and the heels of open step 209 and 210 when the device is in the position of figure 17.
  • the operation is as follows.
  • the hook 200 In its starting position, the hook 200 rests on a board equivalent to the board 7 of the embodiment of FIGS. 1 to 10.
  • the hook is in its lowest position and the lifting nozzles 204 and 205 are arranged just above above the bottom dead center of the trajectories of two knives 211 and 212 belonging to two claw frames animated back and forth in phase opposition, only one of which is visible at Figure 14.
  • the electromagnet 215 is not activated and the knives 211 and 212 oscillate near the nozzles 205 and 206 without being in engagement with these.
  • the hook then remains in its position in FIG. 14.
  • the electromagnet 215 When it is necessary to lift the hook 200, the electromagnet 215 is activated and the rod 216 is pressed down according to the arrow F, as it appears in FIG. 15. Following the displacement of the rod 216, the spacer 217 which abuts against the bar 229 tends to open and its curved ends 217 c and 217 d come to bear against the internal faces of the lamellae or branches 202 and 203 which are deflected simultaneously towards the outside, this has the consequence of displacing the lifting lugs 204 and 205 on the path of the knives 211 and 212. In the position represented in FIG.
  • the electromagnet 215 is activated while the knife 211 is in the bottom dead center of its stroke, and the lifter beak 204 is in the path of the knife 211 when the latter begins its upward movement.
  • the lifter beak 204 hooks onto the knife 211 and the entire hook 200 and therefore the corresponding cord and heald are raised to reach the high position corresponding to the top dead center of the travel of the knife 211, such that 'it is represented in figure 16.
  • the hook 200 In the position shown in FIG. 16, the hook 200 remains in abutment on the knife 211 and descends with the latter when the latter begins its downward movement, to the position illustrated in FIG. 14.
  • the electromagnet 215 is activated and the device is then found in the configuration of the Figure 17. Taking into account the high position of the hook 200, it is no longer the intermediate parts of the strips or branches 202 and 203 which are opposite the curved ends 217 c and 217 d of the spacer 217, but the heels of not open 209 and 210.
  • the hook 200 remains in the high position during the entire downward movement of the knife 211 which corresponds to the upward movement of the knife 212 which, at the end of its travel, slightly raises the hook 200 because the lifter beak 205 is on its trajectory because the upper part of the rod 216 has two divergent surfaces 216 a and 216 b , which separate the lifting lugs 204 and 205 when the hook 200 is in the high position.
  • the knife 212 has raised the entire hook 200 relative to its position when the open pitch heels 209 and 210 rest on the open pitch bars 213 and 214.
  • the open step heels 209 and 210 resume their position of FIG. 16, unless they are again pushed by the curved ends 217 c and 217 d of the retractor 217 d pushed down by the electromagnet 215. If the electromagnet 215 is not activated, the step heels open 209 and 210 escape the open pitch bars 213 and 214 and the hook assembly 200 has a downward movement pressing on the knife 212, until reaching the position of FIG. 14, where it remains until the electro -magnet 215 is activated again so that the retractor 217 pushes the lifter noses 204 and 205 outward.
  • the spacer 217 is an actuator, disposed between the arms 202 and 203, which controls the movement of the nozzles 204 and 205 relative to the knives 211 and 212.
  • a particular advantage of the weave mechanics of this embodiment lies in the fact that, like the lifting lugs 204 and 205, on the one hand, and the open heels of step 209 and 210, on the other hand, are carried by different branches or lamellae, respectively 202, 203, 219 and 220, it is not necessary to deflect the branches carrying the lifting lugs when moving the heels with an open step, as is the case in the modes for carrying out FIGS. 1 to 12.
  • the role of the orifices 202 a and 203 a is here essential since it makes it possible to transmit the movement of the clamp 217 to the heels of open step 209 and 210 through the branches 202 and 203 without moving the latter .
  • the branches 217 a and 217 b of the spacer 217 are provided, at their curved parts 217 e and 217 f , with a central orifice inside which the branches 202 and 203 penetrate when the device is in the position of FIG. 17, that is to say when the lifting nozzles are in their upper position and when the electromagnet moves and causes the spacer 217 to open.
  • the branches 202 and 203 penetrate into the orifices of the curved portions 217 e and 217 f , they do not oppose the opening of the retractor 217 and the latter can fulfill its function without exerting unnecessary effort on the branches 202 and 203. This also makes it possible to limit the power which the electromagnet 215 must supply.
  • the third embodiment of the invention has been described with reference to an electromagnet 215, but the invention also applies with any device capable of communicating to the retractor 217 a sequential movement in the direction of the bottom plate, such as a cam, bar, electric motor system or any other equivalent device.
  • the device 200 of the embodiment of FIGS. 13 to 17 can, like that of the embodiment of FIGS. 11 and 12, be included in a longitudinal box or box, suitable for guiding the base 206, the strips 202 and 203 and l retractor 217, similar to that described with reference to the second embodiment.
